Line shapes of $Ω (2012)$ production in the $Ξ K ˉ$ and $Ξ π K ˉ$ decay channels

Natsumi Ikeno, Eulogio Oset

We theoretically study the line shape of the experiment for $Ω (2012)$ production in the $Ξ^{-} π^{+} K^{-}$ and $Ξ^{0} K^{-}$ decay modes, reflecting the $Ξ^{*} K ˉ$ and $Ξ K ˉ$ decay mod…

$Λ (1670)$ production in the $ψ (3686) \to Λ Λ ˉ η$ reaction

Natsumi Ikeno, Eulogio Oset

We perform a calculation of the invariant mass distributions in the $ψ (3686) \to Λ Λ ˉ η$ reaction, where a neat peak for the excitation of the $Λ (1670)$ and $Λ ˉ (1670)$ in the…

Correlation function for the $n D ˉ_{s 0}^{*} (2317)$ interaction and the issue of elastic unitarity

Natsumi Ikeno, Eulogio Oset

We study the interaction of a neutron with the $D ˉ_{s 0}^{*} (2317)$ resonance and look at the amplitude below threshold and close above threshold. The study is done from the persp…

The role of the $f_{0} (1710)$ and $a_{0} (1710)$ resonances in the $D^{0} \to ρ^{0} ϕ$ , $ω ϕ$ decays

Natsumi Ikeno, Wen-Hao Jia, Wei-Hong Liang +1

We study the $D^{0} \to ρ^{0} ϕ$ , $ω ϕ$ decays which proceed in a direct mode via internal emission with equal rates. Yet, the experimental branching ratio for the $ρ^{0} ϕ$ mode is twice…

$D^{+} \to K_{s}^{0} π^{+} η$ reaction and $a_{0} (980)^{+}$

Natsumi Ikeno, Jorgivan M. Dias, Wei-Hong Liang +1

We study the $D^{+} \to K ˉ^{0} π^{+} η$ reaction where the $a_{0} (980)$ excitation plays a dominant role. We consider mechanisms of external and internal emission at the quark level, h…

On the molecular nature of the $Ω_{c} (3120)$ and its analogy with the $Ω (2012)$

Natsumi Ikeno, Wei-Hong Liang, Eulogio Oset

We make a study of the $Ω_{c} (3120)$ , one of the five $Ω_{c}$ states observed by the LHCb collaboration, which is well reproduced as a molecular state from the $Ξ_{c}^{*} K ˉ$ and $Ω^*_…

Analysis of the $ψ (4040)$ and $ψ (4160)$ decay into $D^{()} D ˉ^{()}$ , $D_{s}^{()} D ˉ_{s}^{()}$

M. Bayar, N. Ikeno, E. Oset

We have performed an analysis of the $e^{+} e^{-} \to D^{(*)} D ˉ^{(*)}$ data in the region of the $ψ (4040)$ and $ψ (4160)$ resonances which have a substantial overlap and require sp…
